How does Capital Gains Tax work on jointly owned property?

If you own a property jointly, each owner is taxed on their share of the gain individually.

Each owner gets their own annual CGT exempt amount (£3,000 for 2025/26), so between two owners you effectively have £6,000 of gains that are tax-free before any CGT is due.

Each owner's gain is also taxed at a rate based on their own income — so if one owner is a basic-rate taxpayer and the other is a higher-rate taxpayer, they'll each pay a different rate on their share. This can work in your favour if the owners are in different income bands.

Ownership is usually split equally (50/50 for married couples), but if you own the property in unequal shares these should be formally documented to ensure HMRC taxes each person on the correct proportion.

For jointly owned property sales, we offer our Joint filing at £449 (two owners) or Trio at £598 (three owners), which covers the full gain calculation and filing for all owners in one service.
